2. Just use a good cleaner and you will be good to go..
I'm new so you can take my experience or not. I've built a few cars in my life and even worked on one or two. I worked for TWR on the engine management for the Jaguar XJ220 and the Arrows F1. I've worked on a few engine management systems here also. I did build some street cars for some rather wealthy people and they all were 200++ mph cars (my new life is something totally different however). Techron is great stuff. It is a detergent based cleaner and that is the key. Red Line is the only other injector cleaner that I know of that is detergent based. The rest are solvent based and can damage the windings on some of the lucus type injectors.
As for the gas additives, those are usually tolulene based and are not very good for anything and are especially bad for O2 sensors. It is much cheaper to go to Home Depot and buy it by the gallon if you are just crazy to get some. It acts as an octane booster. An octane booster does NOT add more BTUs to the fuel, rather it retards the combustion allowing for a higher compression and more advance on the spark. With the new computers I have worked on there is a limit to the advance that is dialed in using algorithms based on load, temperature, map or maf readings, throttle position, etc. During the test phase of engine development the engineers specifically target the performance of the engine to gas octanes. Adding something to the fuel will not necessarily make the engine perform better as the engine has not been tuned to take advantage of the higher octane. The newer computers do not keep adding spark until knock and retard it, they have a limit, again set according to load, temperature, etc.
The best advice has already been given. Use a can of Chevron Techron or Red Line Fuel Injector Cleaner once every few months to keep the system clean. Use a good quality motor oil and change the oil filter often. The only other advice I can give you is to run the piss out of your car. Seriously, that will clean the engine out better than anything. Babying the car is the absolute worst thing you can do to it.
Kind of an interesting quote.
He is right about Techron,that is the best do it yourself stuff you can run through your fuels system on the market..it really works.
Now I am in no way an engineer but it somehow I can`t help think he moves into the "if you can`t astound them with brillance then baffel them with bullshit" area.
I can`t contradict his assertions because I simply don`t know but his statement about retarding combutsion increasing compression is a mis-statement.
Perhaps he means increasing compression or more acurrately combustion pressures.
I am not aware of the company TWR he is speaking but there was a company in the engine parts business several years ago named TRW.
Maybe it was a typo but if that is what he is referring to then to say it wrong twice in different posts makes me suspicious.
I can find no info on the V10 engine he talks of and have no idea how it worked with no camshafts.
